Your platform stays. Your payments expand. Paying.co builds custom payment integrations into the POS and ERP platforms you already use, connecting them to your gateway and your payment devices.
The menu management, inventory, reporting and operations platform you already chose stays as it is. We build the payment layer that connects it to your gateway and devices. Supported versions and interfaces are confirmed during scoping.
Hospitality, restaurants, hotels, stadiums and quick service. Payments need to work at the table, the counter and across properties.
Review the questions to resolve before integrating payments into Oracle Simphony → See Oracle Simphony payment integration scope and delivery →High-speed grocery, convenience store, liquor and specialty retail, where checkout speed and payment reliability matter at every lane.
POS, eCommerce and ERP environments where the default payment connectors do not fit the business.
Read why your gateway or platform should be connected to Odoo → See Odoo payment integration scope and delivery →We keep these two separate on purpose. A path we have delivered before is a starting point, not a promise that it fits every current version, device or region.
Starting from a path that has been built before is usually faster than starting from zero. Whether it fits your platform version, devices, processor and region is confirmed during scoping.
These are proposed as custom work, scoped and priced for your environment.
Devices we have discussed in scoping include Verifone, Ingenico, PAX, Castles, Sunmi and Android-based payment devices. Support for a specific model depends on the platform, the gateway and the processor.
Depending on the platform, gateway and devices, an integration can cover these flows.
Not every platform and gateway combination supports every flow. We confirm which flows are supported for your combination before development starts.
A payment integration connects five things. Knowing who owns each one up front avoids surprises later.
The integration layer is custom software that Paying.co builds and maintains. Whether it carries any ongoing or per-transaction fee is defined in your Statement of Work, and your gateway and processor set their own fees.
Simphony OPI and SPI, Logivision payment interfaces and Odoo provider modules.
In Simphony, OPI is a single payment driver that connects the platform to payment service providers, with tokens and automated settlement.
In Simphony, SPI is a component of the client that talks to a payment service provider, which can be a terminal or middleware.
The right interface depends on your Simphony version, devices and gateway. We confirm it during scoping.
Most delays in integration projects come from missing access, not missing code. These are the dependencies we line up first. Responsibilities below are typical and are confirmed in the Statement of Work.
Understand payment gateway integration scope, timelines, and dependencies →
Timelines depend on the dependencies above, so we assess them before committing to a schedule.
Map platform version, gateway, devices, transaction flows, deployment size and regions.
Deliverable: scope and Statement of Work.Build against the platform interface and the gateway specification.
Deliverable: working integration in a test environment.Test the flows, failure cases and devices. Complete processor testing or certification where required.
Deliverable: test evidence and approvals.Run at a limited number of locations before wider release.
Deliverable: pilot results and fixes.Phased deployment with handoff of documentation and support.
Deliverable: production deployment and handoff.Your team provides access, credentials, devices and pilot sites. Paying.co builds, tests and supports the integration.

If the project requires an EMV certification workstream, see EMV Certification. For testing and coordination on an application that already exists, see Managed Certification.
Platforms, firmware, SDKs and gateways change. Plan for that from the start.
Ownership of the code and the documentation is defined in your Statement of Work.
Support for processor recertifications, platform upgrades and terminal firmware changes, as agreed in your engagement.
A new platform version, SDK release or gateway change is assessed for its impact before it reaches production.
